I am a bit younger so chicken & waffels and a few other CS:S servers were that for me. Also Day of Defeat Source was underrated.

Also, the minigame servers… The mini games people came up with!

1 person shooting cubes at platforms whole others had to stay up, The prison, Piratewars, Multigames (the original fall guys), Prop wars, The one where there were like different power ups behind walls and then have different abilities.

But also battlefront 2 was like that for me. SMD clan with its almost mythical figurehead. Glitching servers, shooting the shit with other people trying to find new glitches. Those were the days.

While matchmaking is good for some games like Rocket League, it has really broken a ton of communities. I think that’s why there aren’t really "clans’ anymore, because people aren’t together enough to organize.
